In the early evening we did the "final soak" where we push the damper in a bit and really reduce the oxygen in the kiln for about 20-30 minutes.
Firing the gas kiln in reduction is quite a balancing act: getting the temperature to rise while keeping the oxygen levels low. Kimberly is very good at it and I am trying to learn the process by shadowing her.
|During the final soak the flames|
come out of the flue trying to find oxygen.
|Pulling the peep shows a lot of "back pressure".|
Once again, the flame is escaping the kiln to find oxygen.
Vince looks on.
|By the time I left, the temperature had fallen|
from 2299 F to 1729 F with a long way to go.
